The project included analysis of over 4000 extra virgin olive oils over three year period. The Aristoil project aimed to determine the extent to which the analyzed olive oils contained a high phenol content (>250 mg/kg). According to European legislation, such extra virgin olive oils can be declared as a product with a positive health effect.
Croatian extra virgin olive oils showed the best health characteristics, i.e. 97% of the collected oils from Croatia had an increased phenolic compound, an average of 655 mg/kg. This result is high above the default 250 mg/kg according to EU regulations.
- Spain has 95% of the oils that meet this requirement, and their average phenol content is lower - 521 mg/kg.
- Greek oils are at about 70%;
- Cypriot at 60%;
- and Italian at 55%, with their average phenol content significantly lower.
